摘　　要：本文对某生物池底板发生的不均匀沉降进行分析和处理。以某生物池底板施工中出现的变形缝上下错位现象为案例,采用雷达探测、钻孔取芯和沉降观测等方法进行了现场检测,找出了主要原因是地基土的冻胀。然后,采取了工程试水逐级加载,并严格控制变形速率和变形量的处理方案,达到了良好的处理效果。最后,根据各种检测方法的相互验证和分析,并结合处理方案和效果,提出雷达探测与冬季施工应注意的问题,为其他类似工程提供借鉴。The analysis and treatment of uneven settlement on a biological poll bottom plate during construction was proposed. Taking the uneven settlement phenomenon on deformation joint of a biological poll bottom plate as an example, radar detection, core drilling and settlement observation measures were adopted to find out the main causes, and the frost heave of foundation soil was focused. Then, treatment scheme for progressive loading, controlling deformation rate and deformation were used to solve the problem, and a good treatment effect was achieved. Based on the mutual verification and analysis, and combined with the treatment scheme and effect, the problems of radar detection and winter construction were pointed out, to provide references for other similar projects.
